Very touristy spot serving forgettable Tex-Mex standards -- not the least bit authentic, along the lines of places like El Torito and Chevy's, and maybe not as good. Better as a bar hangout than a food destination.
The Mex in their Tex-Mex is run-of-the-mill but still worth eating. I haven't been able to find the "Tex" psrt on the menu, save for their BBQ ribs which are outstanding. The portions are large and the prices vey reasonable. We eat there about 4 times a year and have never had poor or even mediocre service. The dining rooms are large enough to handle a very busy tourist (and local) crowd. Parking is abundant and the bar bill won't break you. A word of caution...don't fill up on the great free salsa and chips because you need room for a good meal. You won't be unhappy eating there.
